They went on to state that the combination of hyperthyroidism with a decreased radioactive iodine uptake under special circumstances was clinically diagnostic of SRH and that the thyroid biopsy was unnecessary. That such a complex organ such as the thyroid can be reduced to such well-intentioned, but simplistic, thinking is debatable. Nevertheless, under such circumstances, why resist the thyroid biopsy?Fine needle-aspiration cytology has proved incredibly simple, uncomplicated, and cost-effective. Using a 25-gauge needle, we perform this procedure on an outpatient basis, usually requiring only 15 to 20 minutes. Lymphocytic thyroiditis or thyroid tumors and neoplasms can be interpreted and classified
